To all whom 'if' may concern:

Be it known that l. llonnar A. MYERS, a citizen ot the United States. and a resident of Toledo. in the county ci Lucas and State of Ohio, have made an Invention Appertaining to Automobile `WindoW Litter, which invention is fully set forth in the following specification.

My invention has tor its object to provide an ecient easily operated device tor raising and lowering particularly Windows of automobiles that may oe made at a low cost ot production. rl`his invention also provides an automatic locking device tor securing the window in the position in which it is placed, the locking device automatically releasing the window upon operation ot the manual means used for manipulating the device and automatically engaging upon cessation of the movement of the said manual means. The invention also has tor its object to produce an exceedingly simple counter-balancing device for counter-balancing the Window, that is, a part or all or" its Weight that operates through the lifting device which securely holds the interconnecting parts in Contact and 'thus prevents rattling and enables easy operating the device in raising and lowering the Window. The invention also has jfor its object other 'features and advantages that will appear from the following description and upon examination ot the drawings.

The. invention may be contained in structures AVot different forms. To illustrate practical application of the invention l have selected one ot the structures containing thev invention and shall describe it hereinafter. The structure selected is illustrated in the accompanying drawings.

Figure l ofthe drawings illustrates an edge view of the lifting device, the. frame and window being shown in section. llig. 2 is a side view of the trarne. Fig. 3 is a sectional view taken on the line 3 3 in Fig. 2. Fig. 4 is a sectional view taken on the line 4 4 indicated in Fig. 3. Fig. 5 is a sectional view taken on the line 5 5 indicated in Fig. 3. Fig. 6 is a sectional vienr taken on the line 6 6 indicated in Fig. 5. Fig. 7 is a sectional view taken on the line 7 7 indicated in Fig. Il. Fig. 8 is a sectional view taken on the line 8 8 indicated in Fig. 3.

Fig. is a sectional view taken on the line 9 9 indicated in Fig. 3, and Fig. 10 illu/s trates a perspectivemyiew ot a part of the atuomatic clutch `tor securing' the lifting device. Fig. l1 illustrates a ysectional view, and Fig. 12 illustrates aside of a modification of the means for securing the window in any position to which it may be moved by the lifting device.

The Window lifting device may be used in anypart oit the automobile body trarne for raising any Windows ot the automobile, that is, it may be used for opening and closing the Windows of the doors, or those that are located in the body of the car. ln Figs. l and 2, l indicates a supporting or guiding frame, such as the frame of a door o' the automobile an(1 in which the Window is guided in its vertical movements by suitable guiding channels or strips 2.

The Window 3 is provided with the usual metallic traine t that may extend around the side edges and the bottoni'fedge or may extend merely across the rbottom edge of the Window. The strip et may be made in the` form of a deep channel. ne edge may be bent outwardly with respect to the Win# dow, as at 5, to torna an engaging lip. A. bent bar (l is connected to the litt-ing device so as `to be moved thereby, lChe bar 6 eX- tendsltroin within the plane oi' the inner surface of the Window to the` outer surface ot the channel 4. The bar is provided with an elastic hoolr 7 formed ot sheet metal hav ing an engaging nose 8 for engaging the inner edge of the channel 4. The spring or elast-ic member 7 is preferably made broad so as to have a broad engaging edge or nose 8, as shown in Fig. 5. 'lhe'engaging nose 8 is preferably formed of two parts that are spaced from each other leaving an end edge 9 along the top of the spring member 7 and along the top of the inner edge of the channel 4 and so that an instrument, such as a sereT driver, may be inserted between the edge 9 and the inner edge of the channel,

4- and turned so as to move the engaging nose 8 from the inner edge ot the channel,

lip 5 of the channel 4. When in this posi-` `tion the nose 8 of the elastic hook 7 passes over the inner edge ci? the channel d and thus holds the Window down and so as to against. the end hold the engaging lii the bei: 6. lWhen it ie desired to remove the Window all that is necessary is to .insert an instrument between the elastic inem her 'e' and the channel her' or il end reise the Window so es to reise the inner edge of the eliennel our above the engaging nose S of the spring 'i'.

The bar 6 and consequently the Window il is Connected to the lifting device by ineens of a pair of holte or pins 9 that extend through tivo rollers 1li, The rollers 10 ere located on the oppoeite Sides oie, twisted strip 11 that is preferably formed of bend steel and twisted to produce two opposite lateral spiral surfaces heving the Width of the hand from which the spinal is formed. The rollers are so located that their inner 'contacting surfaces 'will be positioned eport substantially the thickness of the hond. The surfaces et the rollers are preferably barrel shapeend have flaring end edges so es to conform as much as possible to the shape ofl the lateral surfaces and corners of the spiral along the lines of Contact between the rollers and the lateral surfaces of the spiral.. The pins 9 are secured in position by means ofthe flangesor bosees 12 formed on the pins and the nuts 13. The rollers 10 freely rotate on the pins 9 they are moved :along the spiral 11.

The spiral 11 isrseciu'ed et its upper end to a Spindle 14 and et its lower end to e, cylindrical block 15. The spindle 141 and the block 15, and consequently the 11, are pivotally supported in e. :franse 16. The frame 16 may he formed of :i sheet. metal strip bent to form the sides ot en oblong box having en opening 17 in one side, along" which the rollers are moved by the spiral 11. The hi S entends over the edges of the,

opening 17 and a strip or plate 18 is locete het-Ween the edges of the opening 17 and the har 6 and so as to practically cover the portion of the openingq that may he located hetween l(he har 6 and the spiral. The plete 18 is Secured in position by means of the pins 9 through which the;7 extend, the plate 18 and the her G being clamped together by means of the nuts 13. The ende o? the oh long frame or box 16 ere 'provided with metal blocks 19' end 2O that close the ends ofthe hon. The spindle 14.- hes e. hearing; in the 'block 19 and the block 15 is stepped in the hloolz 20. Bells or rollers 21 may he located between the block and the bloei; to support the end tl'iruet of the spiral 11 and at the same time permit pivotal Vmovements of thespirel.

l1 worm-Wheel 22de connected to 'the spindle 14. The Wonne/heel meshes with the Worm-Wheel 23, the axes of the tivo. Worm-Wheels being located et right to each other. A. crank handle, snc

es the handle 241g is conne@ 'fl 23 hv ineens olf the Shank or pin hone/lhis supported for rotating Inovenients in :i part of the frame 1, as illustrated in Fig. Rotation of the crank 2li thus musee rotation of the Spiral 11 which causes i0 the lateral surfaces of the spiral to engage the rollers und niove the rollers aloi'igg the spiral either up or down or according to the direction of rotation of the crank Preferably the direction of the thread of l5 the Worin-gears and 23 is euch that when (he window is being?? lifted, the friction hetsveen the wol-ingeer will tend ,to lift the spiral 11 which will reduce the load or pies sure on the helle or rollers; 21.

'llo counter-balance the otieet oi. the weight of the Window on the lifting device, e menne is provided for j,f'ieldinp;ly resieting the rotation of 'the Spiriti .11 due to the Weight of the Window. A. sleeve 26 ie located on the S Spindle 111 and u long springe,` wire 27 snrrounte the Sleeve 26. `@ne end of the Wire 2 secured in position hy the pin 28 and the other end of the spring iseonnocted to the spiral gear 22. @ne end of the spring im 2'? is rotated Suiieientlv end in such :i direc tion :is to Counter-helen@ the rotiition'oi the Spiral 11 diie to the weigl'it of the '"'iiv dow operating thioiiejh the roller 10l This; prevents the Window .from nioving'dovvn the Pfl Spiral hy its own weight and causing; 't' spiral to rotate, thus prevent-e norn y the dropping; or lowering' of the Winde The Spring Wire 2? ie n, long spring; wire i: t consequently may he rotated through quite a `range of turns without materially oftenting` the conntenholeneing effee'l; of the "Spring, soethat the Window will he held in Whatever position it is 'placed hy the roto tion of the crank 24., which causes the rollers to move along the Spiral 11.

Since the spring 27 is merely n counter haianeing spring it Will not prevent the Window from loweringl "when it is )erred down, which oconswhen the automobile is lli) running over 'the rond. ln oi'der toisoeniely hold the Window in position in which is placed h v the operation of the spiral 11,

l have provided an niitomntio olntoh or lool7 ing1 device. cyl' ndrionl lblock 29 is seen?. to the oblong 'o l. it Surrounds the huh of the gear-Wheel The huh the geen l" rotetee in the evlindrrieel wheel 23 'i block Jil oylii'idrical Shell 30 Surrounds end substantially covers the cylindrical block @Koopt el; one Side which ie provided With :in openingn through the flange of the shell. il ooiledeprine or 'hand 31 is located around the ovlindrieel hlook 29 and Within the Shell The Spring is tightly drown and engages end edfgee of the Nflange oi the Shell in the opening'. `The ovlindrieei hloel: 29 ie thus eiestimilly engaged oy the spring end the shell ie nonielly heini in to the hlool; hjy

Leaaeae the protruding ends or the Wire 31. The

' a square shoulder 33 that fits a square openn ing formed in the central part or the disk 32. The disk 32 has a ingerv34 that is bent over thc shell 30 and is located between the protruding ends of the Wire 31. W'hcn, therefore, the handle 24 is rotated, it rotates the disk 32, which is keyed to the handle through the spindle 25.- The finger 34 is thus moved to the right or left according to the rotation of the handle, and is 'caused to engage one of the protruding ends of the Wire. This tends to unwind the Wire from the block 29 and thus loosens the grip of the wire and at the same time the pressure on one end of the spring by the linger 34 is transmitted to the edge of the opening of the shell 30 on the side of the finger in the direction in which it is turned by the handle, which causes'the shell 30 to lrotate and consequently causes the gear-Wheel 23 to rotate and consequently the window is raised or lowered according to the direction in which the handle 24 is turned. `When the ressure of the linger 34 against either en of the spring 31 ceases, that is, when the rotation of the handle is discontinued, the spring immediately grips the cylindrical block 29 and holds the shell 30 in the position that it is placed relative to the block and thus the gear 23 is securely locked. This prevents the Window from being lowered by such jolting es might overcome the balancing spring 27.

In the modification shown in Figs. 11 and 12 the clutch operates directly on the spiral 11 and its engagement is controlled by movement of one of the gear Wheels. The finger 36 is connected to the spiral gear Wheel 37 which is keyed to the spindlc.38. The counter-balancing spring 27 -is connected to the gear Wheel 37 in the same manner that it is connected to the gear Wheel/22 in the form illustrated in Figs. 3 and 4, and operates in the same way. A cylindrieal member 39 is secured to a part of the container or oblong box 16. The fixed cylindrical member 39 also forms a bearing for the block 40 which is connected to the upger end of the spiral band 11. The sccon ycylindrical member or cup 41 is keyed to the block 4() and is thus connected to the spiral band 11. The wire band 42 is constructed and located with reference to the cylindrical members 39 and 41 the same as in the structure shown in Fig. 3, the-memn ber 41 having an opening 43 on 'one side thereof through which the ends 44 ofthe band spring protrudes. iThe finger. 33 is located between the ends 44 of the spring 42 and so that when the spiral gear 23 is rotated it will rotate the spiral gear 37 and move .the iinger 33 to the right or the lett to engage one of the ends 44 of the spring 42 and thus'tend to unwind er loosen the spring in its engagement between the edges oit-the opening 43 and the cylindrical member 39, which will at the same time rotate the spiral `11 to raise and lower 'the window.

'When the spiral gear 23 ceases to rotate the engagement is made between the'lxed member 39 and the cup 41 which locke thev spiral band in position and thus-locks the window. The balancing spring 27 also operates through the spiral gear 37, but the force or pressure produced by the balancing spring 27 is not sumciently .great to canse the rotation of the spiral band l1, but is sufficiently great to prevent the rotation of the band il by reason ot the weight of the Window. f.

1. ln"- a Window iifting device, a spiral 'metal band, rollers connected to the rvirn dow, a rotatable member for rotating the spiral band and a clutch mechanism con` trolled by the rotatable member for lock ing the Window.

2. ln a Windowu lifting device, a vertical rotatable member connected to the window for raising and lowering the window, means for rotating the vertical rotatable .member a. locking device for locking the rotatable member in position, a counter-balancing spring directly connected to the rotatable member for counter-balancing the Window'.

3. 1n a window lifting device, a, spiral band for raising and lowering-the window, a rotatable member for operating the spiral band, a locking device for' locking the rotatable member, a counter-balancing spring connected to the spiral band for counterbalancing the weight of the Window.

4. In a window lifting device, a window supporting structure, a screw member, a means for actuating the screvv`member, a, member connecting the Window'with the screw member for actuating the Window, a locking means for securing thc window in the position into which it is moved and connected to the screw member for locking the screw member against rotation. a removable frame for supporting the screw member, the locking means and the actuating means and for guiding the connecting means and means for securing the frame in position in the Window supporting structure.
